Indirect leaching, in contrast, does not proceed through a frontal attack, by the bacteria on the atomic structure of the mineral. Instead the bacteria generate ferric iron by oxidizing soluble, ferrous iron; ferric iron in turn is a powerful oxidizing agent that reacts with other metals, transforming them into the soluble, oxidized form in a sulfuric acid solution.
